How can you tell if two fractions are equivalent?

Two fractions are equivalent if the fully simplified fractions are equal. If you can multiply the fraction with the smaller numerator and denominator by the same value to equal the second fraction. For example the fractions 3/4 and 9/12. The nominator and denominator, 3 and 4 have both been multiplied by 3 to equal 9/12. Cross multiply. If the products are equal, the fractions are equal. Cross multiplying means to multiply each numerator of one fraction with the denominator of the other fraction.
